Emergency pasta sauce

This was created when I had nothing in my cupboard apart from an onion, pasta, tomato sauces and seasonings. The ketchup gives it a slightly more interesting taste than just watering down the concentrate. Dried herbs = mixed herbs = sage, thyme, marjoram, oregano and parsley

For what this is, it is definitely a winner. I had some leftover pasta for lunch, and didn't want to open an entire jar of sauce just for one serving. I used tomato paste, italian seasoning and added a pinch of garlic powder and onion powder as well. Cheap and easy, thanks!
